This is a new project commissioned by Emily Violet Frisch, check out her work on INstagram @emetvarda and thank you Emily for your patronage. Hopefully this video is a little better quality than the last two, so please comment, critique and definitely subscribe (it helps me step up my game!). These were two pieces of granite I found in our fieldstone pile that I made into a mortar and pestle type of bowl.

Please hit that subscribe button and inspire me to create new and exciting pieces. Two ideas I have on the boards are a stone sculpture, maybe a Griffen, Lion or an Owl and some stone carved shelve brackets.
Jason Michael Kotarski I have a question do you think this would be possible without power tools?
@@Pcgamingfixes duh, just be way harder
@@Pcgamingfixes Sorry, just saw this! Yes, the star drill is the old method, I think it's the chisel I was sharpening at the beginning of the video? Maybe? I have chiseled stones by hand when recreating architectural elements for historic architecture and I will say it takes FOREVER...and alot of hammer arm grease and chisel sharpening. Granite is a very durable material and as such requires very durable working tools!
@@allenyao6685 ......and takes way longer.... but it is possible!
Done... :-)
I think it's very nice. Love how natural you kept it.
Thanks Angie, yea hard to compete with nature on beauty eh? Better off Laissez-faire!
LOVE Love love = i want a large one as i miss my great great great grandmothers stone bowl i use to have ....
never seen a new one before. we handed down so long that many were many hundreds of years old - we had a few types. Love this shape - very good.
Thank you! (and Thanks for Subscribing :)I can ship them via USPS Flat Rate in the US. Small, Medium & Large, roughly the same size as the flat rate S, M, & L
Man. i cut the same stone mortar and my family is going crazy with the smell i have. This mortar runs perfectly with 3 or 4 pieces of garlic a small amout of salt ,lemon juice,parsley and cilantro, all mixed with some oil and some toasted bread to spread on... it is magic...every one runs away!!But who cares. THANKS MAN .
Alx li Sounds (or Smells) like a success!!! There is a certain "old world" feeling using this versus the electric type, CONGRATS!!
Sounds tasty to me
Awesome Job! Thanks For Sharing! :) bowl looks so Beautiful. I really want to get into Stone work! Loving these videos! Thanks for uploading & sharing your work with us!
Thank you, honestly its my honor that anyone even watches my shenanigans!!! I just hope I impart enough information for you to be safe AND successful with a project!.....
Great work Jason -- loved the finish!
Nano Taboada Thanks Nano! I think it was the million years and moving glaciers......but I'll take a little credit, lol!
That is an awesome idea with the wood . Thanks for teaching me something
You mean the block for grinding the the pestle? I actually planned to make rollers but haven't been making these lately, too many other projects going on!!!
Jason, beautiful stone work! you inspire me to try it myself.
Thank you! And that is much appreciated, good luck! It's so much more rewarding when you can make things yourself....and it's a fun conversation topic at a dinner party!
I want one. Goodness!! Nice video.
Thank you. I haven't made one in awhile and I think I took down the Amazon listing. I might do some more again in the future but definitely not this Winter!!!
Thats awesome
Creativity is a beautiful gift
Thank you! I am lucky for that (well sometimes, sometimes it leads to some crazy ideas!)
Absolutely beautiful
Thank you! Please subscribe, I've been doing construction videos lately but I have a couple sculpture projects and a furniture project in the works!!
I'd be happy to be your 1000 sub! Congrats, now go get that YT money. Nice work on the granite. You gave me some great ideas for my bronze artwork!
worldtraveler Thank You!!!!
Beautiful work. I have leaned how to use angle grinder.
Thank you, I have one for stone, one for wood and one for metal, it is the most used tool I own!
That’s a beauty ! Thank you great job !
Thank you! I'm planning some smaller jewelry pieces pretty soon so stay tuned!!!
Excellent work! I'm deffo going to give that a go sometime
Thank you Philip! I hope you do! That's why I make these videos, good luck and be safe, those blades look dull but if they cut through granite.....
And granite is HARD ! I'll take my time and give it plenty of practice
thanks for the video. i am about to start similar work on a chunk of granite.
Great! That's really why I make these videos. I have some bigger stone carving projects lined up once I get the back log cleared. I hope you stay tuned. If you have any questions feel free to ask, I'm also putting together a Q&A for my channel if you care to check that out, it's the Interview Questions video. GOOD LUCK and be careful.
Will do thanks for the info. I am really glad I found this.
Nice work
Thanks!! Seems like forever ago
Nice work, thanks for sharing. I make similar pieces with a variety of stone. One caution; that stone dust WILL destroy your lungs if you don’t wear high quality dust masks AND use a strong fan to blow the dust away
Definitely! P-100 respirator is my everyday PPE, also adding h2o to keep the dust in a slurry adds life to the cutting tools!
Very nice work...
Thank you, Sir!
That's pretty cool!
Thank you Connie!
Excellent video
Thank you! When I get the new computer build finished I will have alot of new content coming up!
super! thanks for posting!!
Thanks & My pleasure!
hard core man like wow!!!!
Thank you! Just a day in the life.....
So cool!
Thanks! Haven't done one in a while but they're great for hard to crush things
Wow inspiring piece bro
Thank You! They were fun to make!
Parabéns lindo trabalho
Obrigado!!!
Lindo tu trabajo...🖒
Joshi Nanco Nanco ^^^Mucho Gracias!!!!^^^
Hermoso trabajo
¡Gracias! Fue divertido hacerlo
Aku juga punya lumpang/lesung dan alu granit alami .dan sangat lucu..dan berat sekali meski batunya kecil
Very nice! Going to start making one soon with a chunk of blue stone I found. What was the disk you used to polish the pestle?
daniel van boom Great, that's why I make these! The polishing discs are diamond grit polishing discs. I think I listed them on my blog and in the description but if not I'll look for it again. I added a water fed grinder that's been nice for polishing.
Lovely price. Could you do some explaining on you next video. I saw you using water while sanding and wondered why. How do you polish the stone to make it shine ?
Thanks Lynda! The water helps reduce friction between the diamond grit pad and the stone giving a smoother, cooler, finish (and keeping the dust down). I have a new water fed grinder for the next one and I will do a voice over or in video explanation.
good job bro! nice device..
Thank you much!
very good
Excellent
Thank you! It means alot to me for someone to take the time to comment let alone watch my videos!!!
Amazing
Thank you! They were fun before they became so popular.
Brilliant
robin roberts thank you! It was fun (well kinda fun)
Hola de Perú 🇵🇪🇵🇪🇵🇪 Muy lindo lo felicito 👏👏👏
Hola de Seattle!!! Muchas Gracias!!!!
Beautiful work! For a food processing accessory, granite may not be the healthiest choice.... it is known to emit Radon gas. Another stone could be chosen.
Thank You! I never thought about that, I wonder what the ppm of Radon could be? I wonder if it would even be measurable?
If you have ever spent more than 10 minutes in a basement than you have exposed yourself to more radon than a granite mortar will ever put in your food
Nice!
Thank you! Cheers!
Nice results. What is the tool used other than the angle grinder with the diamond blade?
Thank you for the compliment. I think I wrote the tools down on the blog. 3lb hammer and a pointed chisel ( I also have carbide chisels and a pneumatic but I didn't use them on this). Also, a diamond cup wheel and diamond polishing pads
Se puede hacer un mortero de roca o canto rodado de cuarcita aplicando la misma tecnica. Gracias saludos

¡¡Absolutamente, es una práctica antigua !!
hello nice job! I have a question did you use the tungsten grinding disc for the polishing?
Thanks Nacho!! No Tungsten on the granite. Tungsten is one tough metal but it would shatter on granite. The cutting, grinding and polishing discs are all diamond grit.
Hi Jason, great video! I'm working on a similar project and I was wondering what kind of disc you used to grind out the bowl. I tried a tungsten carbide one but I'm afraid it's still not hard enough for my porphyry block (yes, not the easiest stone to work).
Thanks :) (I couldn't find the tools list on the blog)
You'll need a diamond in-bedded blade for masonry. My other stone carving videos are less video quality but I talk about the tools more. The blog was hidden in the archive list,
jasonmichaelkotarski.blogspot.com/2017/02/stone-carving-granite-fieldstone-mortar.html
The blog has links to those items and I think I went into greater detail on the other videos in the description. Be careful working with stone can be dangerous, fingers, eyes, ears, lungs, etc.... wear ALL the PPE and use water if can.
thank you!
How about guards on grinders? Do you recommend those? What about for "workers" in "developing countries" where this sort of thing is done on a mass production basis and the "manufactured goods" are then exported to "developed countries" where lying assholes sell it as their own "craftsmanship"? What kind of PPE do you recommend for those poor suckers getting bent over by racist shitbags making a quick and easy buck?
Hi, good work. Tell me if you can carve that rock with copper chisel?
If you mean a chisel that is made to carve copper, perhaps. If you mean a chisel made of cooper as was the case in prehistoric times, I would think it would take a lot of time and you wouldn't have a chisel left when you were finished! I use two types, hardened tool steel and carbide tip chisels from Trowe and Holden Co.
Thank you for the compliment! I hope this inspired you to make one!
Super done, but alot
hard and dusty work.
I work with almost the same technique, but with another raw material and I make something completely different and it will be seen for the first time on YT, .. soon on my channel :)
Thanks, yes it is alot of work and a little water goes a long way keeping the dust down. Cant wait to see what your working on, good for you!
Jason Michael Kotarski ...ok! thanks for commenting on my writing, and of course thank you for your interest in my future project, ..p.s and i can't wait to get started :) all the best! 👍
Of course! That's why I make these videos!
Jason Michael Kotarski .. I told you I was going to present a video about making pots of other material and I just posted it, so I want to share it with people like you .. all the best!

I love working in natural stone
I as well, something about the age of the stone and the permanence of the piece. I found a quarry not too far from here that has some decent sandstone I am trying to get my hands on for some larger sculpture/ architecture pieces.
Sandstone, huh? For "achitecture"? That should be interesting. Better leave it indoors.
Hi Jason, I enjoy your videos and am new to stone carving. I bought a 45 rock to make into a pestle and mortar, but I was wondering if there is another way to make the concave bowl part? Or is the angle grinder pretty much the only way? I hope to keep my hands and fingers so I can carve forever. I brought my stone home with me but I think I will ask my teacher if she can help me do it :D Thank you!
Thank you! I thought about doing a heavy duty video but maybe I should do a light duty one! The grinder is the smallest tool that does the most amount of work. A lathe and carbide stone chisel would be the industrial step up. A drill press with a core drill would be an option, or a large drill with the stone clamped down. Anything else just takes a lot longer, star (+ shape) drilling chisel, a dremel tool, etc...
Just make all the videos :) we love and need them!
Saw in the comments that you have a new water-fed grinder - is this one just your typical angle grinder? I just picked one up to complement the flex shaft I'm getting for Christmas and I'd been wondering if it would be dangerous to use with water, but it appears you've been chugging along with a typical grinder and water for some time without issue. If so, any tips for doing so safely?
Hi kim! The h2o grinder died before it ever even did anything so I'm back to the 4 1/2". Honestly I typically only wear a P-100 respirator plus ear protection and either safety glasses or a face shield. The last one and the one I am on today I dry cut the "star" pattern and chisel out the pieces, fill the small bowl with h2o and continue on cut/add h20, cut/ fill with h2o, etc... and its been fine. A water proof bib would be ideal as it throws some wet slurry in a hurry!
Make sure your slow and steady with your cuts, with a good grip so the blade doesn't bind and twist your wrist. Always ease into the cut paying attention to the amount of contact the blade has and how deep it is, ie. At first only 1% of the blade is in contact and slowly increases to roughly 45% when completely plunged. The beginning danger is the blade wants to bounce around , when its fully plunged you must keep it straight/even/plumb so it doesn't bind on the sides and snatch your wrist or jump out at you.
Practice with the wheel direction, if the blade spin is away from you so is the debris, but the blade wants to jump towards you. If you have outdoor space a fan can help move the dust away from you.
Good Luck!!!!
I'm interested in the wooded block you're polishing the Pestle in, around 6:30. How was it designed, and how does it work?
Thanks Stephen, so the wood block was my latest idea, ive done something similar for timber framing. This one is simply a rounded notch that should fill with water, lubricate the stone while the grinder spins the stone like a lathe. I'm working up another model that has bearings and rollers.
Stephen Wise Thanks Stephen, its just a rounded (ish) notch that lets the stone spin with the grinders friction. I'm working on one with bearings and rollers.
Ah. "Timber Framing". All the rage several years ago and suddenly there were "timber framing contractors" everywhere. Apparently now its "stone cutting". Its amazing how VERSATILE some "craftsmen" are, isn't it? You mentioned in another comment that this video is simply "a day in the life". How does one go about getting a "life" like yours?
Hi Jason, can you please tell me what kind of wheel you used when you turned the piece around to flatten underneath? Thanks in advance.
In the description is a blog post with links
I looked up the blog last night but could not find it. Will look again.
It's buried pretty deep, it was an old blog post, sorry I will up date the link in the description. Good luck!

Im just curious, on other videos i saw people make a grid of relief cuts for the inner bowl portion but your relief cuts were more like a pie, was there a reason you did the cuts in that way or was it just personal preference?
Hi! The only thing I can think of (in relation to other videos/ makers cutting grids) is that it may be the size of the piece being worked. Simply put,I try to cut the pieces best fitted for where I want a fracture to happen. The pie shapes are simply the geometry of cutting a 6 inch circle with a 4 inch diameter blade. The less cuts I have to make means less dust and wear on the blade.

Incredible work. Great video. Subscribed - keep on keepin' on!
Greg H Thank You! I'll get back to making some videos of projects as the weather is finally cooperating!
Just now coming across this. Well done! What do you use if you would like a more finished surface?
Thank you. More polishing discs, lots of water and patience!
@Jason Michael Kotarski so I'm looking at attempting to do this for the first time so forgive me if I am asking too much but what kind of polishing disc's? Is it a specialty type? Thanks again!
Yes. They diamond polishing disc's. They go from 40-50 grit up to 3000 and the Buffing.
@@JasonMichaelKotarski much appreciated! Keep up the good work!
Think how long it would take with useing no eletrical tools? Also all the dust would need to wear a somekind of respiratory and how did the blade not over heat?
I've chiseled a few stones in the field ( historic preservation jobsite, not farm type field) and it is certainly an endeavor! Someone asked why I didn't do a hand carving job and I simply replied, too many projects, too little time, and lots of new technology.
A respirator is absolutely necessary for dry cutting, I even wear one while wet cutting in case theres a hiccup w/ h2o supply. P100 is the benchmark for most everything. Ears and eyes as well!
The blade will over heat but this is a small project. Water is ideal for any stonework. In
Im trying to find the toughest material to make &/or purchase a mortar and pestle for grinding up small rocks to make pigments for paint. What is the best material to use for this?
Jennifer Guecho Granite is one of the hardest that is still workable. Which stones are you going to grind?
Jason Michael Kotarski I'm not too sure of the names but something hard like broken down rock sized pieces of a brick
ahh... I've heard of that. It is definitely hard enough to crush historic brick or older brick. Newer brick or clinkers (old bricks fired hot for road pavers) that are kiln fired to a high temperature will be more difficult but again granite is harder. For your particular project you may even be able to use high strength concrete. They concrete however could possibly taint some of the bricks color with gray though.
Stag beetle very good point, not all granite is the same and depending on quartz veins and flecks of feldspar every stone can be different. These for example are glacial till from the Cascade Mountains in Washington.
Hey, what type of disc did you use to cut and what one did you use to sand it ? Thanks
Hey Josh, I'm not sure which brand I used but they are called diamond cutting disc blade, diamond cup grinder, and diamond polishing pads.
thank you very much.. it's splendid... ! :-) why not as well trying to create small/tiny rough bowls (8 to 10 cm diameter) for indoor succulent plants...? I had paid quite expensive price for these artsy succulent pots from Amazon, and they even not as genuine like your natural / real stone (it was faux stone pots made from ceramic..).
Thank You!!! hmmm. That's a great idea! To be honest, I thought these were small!! I'll have to find some smaller tools but that could be a good additional item, I'll see what I can do!!!!!!
@@JasonMichaelKotarski here the faux stone succulent plants.. thought if it made from the real / genuine stone will look better and more special.. :-)
www.amazon.com/T4U-Distinctive-Sucuulent-Planters-Containers/dp/B071X9FYVB
Where can I get the grinding discs you used doing this?
Tool links on my blog in the description are Amazon Affiliate program items. Otherwise your local hardware store or Harbor Freight if you have one. They're much more common and readily available nowadays.
👍🏻👍🏻
Does polished part get scratches with pestle is rubbed on it?
Only if your grinding diamonds!! So the polished mortars do not scratch, however feedback from users and myself is that the polished mortars were too smooth and the herbs, seeds, etc... would slide around and sometimes up and out of the mortar instead of grinding. I began roughening the bottom half with a stippling technique that was more favorable for use.
@@JasonMichaelKotarski thankyou thats helpful! Is this is granite stone?
Yup, they're mostly always granite. I've been wanting to try some basalt but I haven't yet.
I have a mortar that is made of stone but has light rust on the interior. What should I do to restore it?
Thanks!
It has light rust? From the stone or something that was stored in the stone? If it's from the stone that would indicate the stone possesses some ferrous metals, ie. iron ore, which is a common occurrence. If it doesn't wash out/off with water and stainless steel pad, iron oxide (rust) is converted/cleaned with phosphoric acid. One brand is called Ospho and I use it regularly in metal conservation. A household item you may already have would be in a can of soda, read the ingredients and see if it says phosphoric acid (that's a big reason why you shouldn't drink soda!)
After you get it cleaned up you should probably wipe it with a paper towel and vegetable, olive, or mineral oil. Then grind up some garlic, herbs and oil with some salt and start getting it back to work!!
@@JasonMichaelKotarski Thank you so so much for your quick and detailed response!
I will definitely look into this!
Please subscribe! It really helps and it's free!!!
That's an interesting "sharpening" technique you use at the beginning of the video. What is the "technical" term for a "pyramid" chisel like that, anyway?
Thanks! The chisel is called a Star Chisel or also a Drilling Chisel. It's used by hitting it and turning before the next blow so that the angles of the star hit a different surface and the stone pieces can fly out of the flutes in the chisel. It takes a long time to drill a hole like this so I rarely use it anymore!
Hola me podrían decir como se llaman los discos que usa?
muela abrasiva y de corte de diamante
How cod I buy good quality and 8" and 7" deep mortal and pestle
I can make them to order in the Greater Seattle Area, Shipping that size mortar and pestle is expensive so it would be an additional charge on my Amazon Handmade store. The price on there is for approximately a 5" deep mortar.
Plastic sheeting isn't exactly an ideal surface for a workbench covering if you don't want the "work" you're "working" to move around, is it? And how did you "cut" that stone bowl all the way down to the CENTER of the bowl so smoothly with a 6" wheel like that? Gotta be one or two "hand tools" here we're not seeing in use. And how did you start with such light-colored "natural stone" and end up with something so dark?
The plastic is a garbage bag filled with sand to adsorb the impact of the hammer and chisel, it's actually very ideal. That was cut with a 4 1/2" grinder wheel, repeating the process of cutting and chiseling will get you as deep as you can go as long as you can hold on to the grinder.
That stone was buried in the ground and covered in clay. Once the clay is washed off that's the color of the stone, Iike the surprise but when someone wants a specific stone or color I have to wash them first and do a test patch to see whats under the clay!
LOL Lovely peice.
I was wondering how you knew the price! It was a good price plus trade for a painting I never got, still a good price AND piece! Thanks for watching!
I want one
Right on! I'm behind on orders at the moment but I have some nearing completion.
Que discos usaste
Should be in the description but check back soon, I'm getting some disc's with my logo on them to sell.
Hey man! really cool! Would it be possible for you to make me one, something 1.5 times larger. Will pay in advance for making and shipping to NJ. Please let me know. Have liked and subbed, and obviously commented.
I can! Send me an email at Jason.M.Kotarski@gmail.com and/or Jason@JasonMichaelKotarski.com and I can send you some measurements of the stone I have available.
Thanks for the L/S/C!
Sent you email Jason.
Do you sell your stuff?
James Goldberg Some sell, some don't, I've been trying to put them in some herb stores around town. I also have an Amazon store but haven't stocked it very well since we had the baby. This one was commissioned so it "sold". They are a pain to ship though, I try to keep them within USPS Flat Rate sizes.

Its amazing how people that use handheld power tools and make "handcrafted" things for rich people and government buildings and the like are "artists" and you can get paid large amounts of money for doing very simple "work" or even selling the "work" of others if you're "crafty" enough to "market" it correctly and aren't above telling lies to make a buck and you're willing to import "cheap" manufactured goods from "overseas" and put your name on it. But if you use handheld power tools to make anything for "industry" or the "private sector" you're a "worker" and you just get to work your ass your whole life and any "government work" you do will be for or as the LOW BIDDER.
I think I agree with you there. I"m often dismayed at the perception of the working class in America. One of the reasons I even started this channel was because I realized that many of the traditional building skills are being lost and it is getting harder to find skilled craft. I think I was born in the wrong century or something.
My hope is that there is a change in perspective and that is why I continue to create things. I want that piece of furniture with a ding in it from the kids riding a bike in the house, I want to see that accidental slip of the chisel or planer mark. We live in a world of CNC milling and 3D printers. I prefer to shop at farmers markets and buy handmade goods whenever possible!
Are you mute, or just not smart enough to include your voice in a how-to video?
